VENTILATING-SCREEN.

To all whom it may concern:

Be it known that 1, Ann CLARENCE HOUGH, a citizen of the United States, and resident of J anesville. county of Rock, State of Wisconsin, have invented an Improve ment in Ventilating-Screens,-of which the following description, in connection with the accompanying drawings, is a specifica tion, like letters on the drawings representing like parts.

The present application relates to a modified form of my ventilating screen invention, as described and claimed broadly in my Patent No. 1,218,556, issued March 6, 1917. The'present application is a divisional of my pending application Serial No. 147 ,7 90, filed February 10, 1917, in which pending application I have elected to claim one form of my ventilating screen construction. In the present divisional application I have elected to describe, illustrate and claim the form of my ventilating screen construction which includes a combined spacing and warp binding element between the slats constituting the ventilating portion of my screen. While I prefer to construct a woven screen having a nonventilating portion in combination with a ventilating portion or portions therewith, it will be readily understood that I may con struct a screen embodying the present invention comprising exclusively a ventilating construction. One of the important ad vantages of the screen utilizing a combined spacing and warp binding element consists in the ease and facility with which such a screen may be built; in the firm, secure and permanent manner in which each slat is held, irrespective of the spacing therefrom to adjacent slats; and in the further important feature of enabling a variation in spacing to be made wherever desired.

Further features of the invention, details of construction, and novel combinations of parts will be hereinafter more fully pointed out and claimed.

Referring to the drawing illustrating a preferred embodiment of the invention,

Figure 1 is a fragmentary view of a ventilating screen embodying the invention;

Fig. 2 is a cross sectional view on the line 2 of Fig. 1.

Fig. 3 is an enlarged detail between adjacent slats, and the combined spacing and Warp binding device, shown in cross section.

Specification of Letters Patent.

Patented Nov. 20 1917.

Divided and this application filed June 8,

Serial No. 173,631.

Fig. 4 is a cross sectional view of a modification.

As shown in the drawing, Fig. 1 comprises a portion of a ventilating screen hav ing a non-ventilating portion, consisting in the relatively broad slats 1, 2, 3 and -1, closely woven by pairs of warp cords or strands, 5, 6, 5, 6, which may be of any number and constituting any desired proportional part of the screen, together with a ventilating section. This ventilating portion comprises a plurality of slats, preferably narrower than the slats constituting the non-ventilating portion, which slats may be variously spaced and are here shown, for the sake of example, as a set of slats 7, S, 9 and 10, being spaced substantially equidistant from each other and slats l1 and 12 showing a greater spacing.

It will be understood that in a woven screen it is necessary to have the warp cords or strands tightly interlaced about the slats in order to prevent the slats from becoming loose and working endwise. This has been one of the diliiculties to be overcome and I accomplish this purpose in my pres ent form of ventilating screen by providing combined slat-spacing and warp cord bind ing elements as indicated at 13, 13. These elements may be of any desired length, such for example as those illustrated at 14;, giv-- ing greater spacing, and they hold the slats spaced in their predetermined position while tightly binding or clamping the warp cords thereabout. These spacing and clamping elements may be, also, of any desirable ma terial, and may be either small tubular members, or split tubular members, the latter being clamped about the warp strands firmly binding them in position during the manufacture of the screen. Fig. 3 clearly illustrates the binding and spacing feature of such elements. I find that tubular strips of celluloid, cut into suitable lengths and split,are capable of advantageous use for these elements. Also similar metallic elements may be utilized, and clamped into position as each successive slat is incorporated in the screen. In using celluloid or the like plastic material, the element can be applied while in a plastic state, and thus more firmly and solidly unite and hold the warp strands and space the slats from each other, a suitable tool serving to apply and force the material while plastic into shape.

I have shown at and'21 the usual reinforcing-y strips about the topmost slat 22, and it will be understood that such reinforcing strips may be applied at different. places throughout the length of the screen,-

curely and permanently binding the spaced slats in their position.

In the modification illustrated in Fig. 4, I have shown a further advantage incident to my type of combined spacing and clamping device. This consists in making a ventilated screen, or a. ventilated portion in a screen, without interlacing the warp cords about the slats, but by relying upon the clamping devices to secure the same. Referring to Fig. 1, the slats 30 and 31 are secured by thewarp cords 32 and 33 running alongside said slats parallel with each other and on the: same side, being engaged, clasped and clamped by the sleeves 35, 35, about the cords, as shown. It will be understood that in view of this modification I do not intend that the term woven screen should be lim ited toa weaving of the warp strands interlaced about the slats, but may apply equally to the construction illustrated in Fig. 4. This arrangement of having the warp cords running parallel or on the same side of the slats, maybe utilized only 'for the ventilating section, if desired, and then interlaced forwardly and backwardly or to and fro about the remaining slats in the non-ventilating section.

My invention is further described and de fined in the form of claims as follows:

1. A woven screen of the kind described, comprising a plurality of transverse slats held together by woven warp strands interlaced over the front-and bacle of alternate slats, in combination with a combined spacing and strand holding element engaging the warp strands between adjacent slats.

2. A woven screen of the kind described, comprising. a ventilating portion and a nonventilating portion, said ventilating portion consisting in a plurality of transverse slats held together by woven warp strands interlaced over the front and back of alternate slats, in combination with a combined spacing and strand holding element between each slat.

3. A wovenscreen of the kind described, comprising aplurality of ventilating portions and a non-ventilating portion, each ventilating portion consisting in a plurality oftransverse slats held together by woven warp strands interlaced over the front and back of alternate slats, in combination with a combined spacing and strand holdingele ment between each slat.

4. A woven screen of the kind described, comprising a plurality of" transverse slats spaced from each other atvarying distances, and being held tightly together by woven warp strands interlaced over the front and back of alternateslats, in combination with combined spacing and .str'and clamping sleeves, the length of said sleeves determin}v ing the spacing of adj acentslat's;-

5.'A woven screenof the kind described, comprising a ventilating portion and non ventilating portion, said 'nonventilating portion consisting in slats held closely together by woven warp. strands interlaced tliereab'out, said ventilating portion having the slats woven farther apart'than the nonventilating section, andso woven by said warp strands as to permitthe said ventilating section slats to be spaced from each other and from the end slat of'the non-ventilating portion, in combination'with means engag ing the warp strands between each of'the slats in said ventilating portion to hold'said warp strands tightly in enga'gementwith, and spaced from, adjacent slats. 7 j

6. In a woven screen, a non-ventilating, closely woven portion, comprising a plural ity of transverse slats held" together by woven warp strands, and a" ventilatingportion, comprising a'plurality of transverse slats held together with the warps running parallel, and combined warp engaging andslat spacing devices, claspingsaidwa rp strands between the spaced slats.

7. In a woven screen, a non-ventilating, closely woven portion, comprising a plurality of transverse slats held. together by woven warp strands, interlaced overthe front and back of alternate slats, in combination with a ventilating portion compris ing a plurality of transverse slats with'the woven warp strands non-interlaced, a combined spacing and strand holding element between each of said spaced slats encompassing and locking said warp cords tightly about adjacent spaced slats.

In testimony whereof, Iha've signed my name to this specification, in the'presence' of two subscribing witnesses.
